Let me add more fuel to this:

Have you done Garry questline? In short, there are more than one individual who dress in suit and have blue eyes. Some sort of cyberpunk MIB organization.

It certainly thickens the plot that the Blue Eyed Man has an established connection to the Peralez (who are being manipulated by a Security Agency front) and vaguely in the ramblings of Garry the Prophet (who was apparently attuned to their networks with an implant). If nothing else, it colors my perception of the "Path of Glory" ending for V in that we end up working for a pretty evil entity who is behind a lot of suffering. Granted, it's done with the intent of finding a cure but we're still trying to make a deal with the proverbial devil. Better then, I think, to go the way of the Nomad - accept Fate among a Family of your choosing.

While I'd love to deal with this organization further, I feel that the Blue Eyed Man's overt similarity to the ME2-ME3 Illusive Man means that he's little more than a cameo apparent.

Mr. Blue Eyes is probably a Rogue AI that controls the host body via something similar to a doll chip (or maybe even via technology similar to the Relic). I think the customer/guest list from the casino might contain another Rogue AI that needs to be freed, similar to Johnny Freeing Alt Cunningham before blowing up Arasaka Tower. Wouldn't surprise me to see Morgan Blackhand and Spider Murphy teaming up with him in Crystal Palace.
It does make sense, however, that V gets into an agreement with him: He obviously has access to the technological means to alter the neurological composition of the human cerebrum, an ability that might provide to be V's last hope of survival.
